Chains	Enzyme Name	Description	Catalytic Residues
A	alkaline phosphatase M-CSA #44	Alkaline phosphatases are zinc and magnesium containing metalloenzymes which function optimally at high pH. They are found in all organisms except some plants, in the periplasmic space (E. coli), in vacuoles (fungi) or GPI-anchored to the external cell membrane (mammals). Alkaline phosphatase-type activity is involved in many cell processes, including metabolism of glycerolipids, folate, and xenobiotics. They cleave phosphomonoester bonds from various substrates, such as the end of a DNA molecule.
